NICHE Drive Sprocket Chain Combo for Kawasaki Ninja 300 EX300 Z300 Front 14 Rear 42 Tooth 520V-X X-Ring 106 Links
This combo is sized specifically for the Ninja 300, pairing a 14-tooth front and 42-tooth rear sprocket to match the stock gearing exactly, so there's no guesswork on fitment. The 520V-X X-ring chain offers better dirt and moisture sealing than standard O-rings, which suits the 300's typical commuter and weekend use. Caveat: the 106-link count may require removing one link depending on your swingarm adjustment position.
